COMBINED TYPE-WRITING AND ADDING MACHINE.

Specification of Letters Patent.

Patented Sept. 3, 1912.

Application filed December s, 1904. Serial No. 235,980.

To all whom it may concern:

Be it known that I, VILLIAM H. PIKE, Jr., a citizen of the United States, residing at Orange, in the county of Essex and State of New Jersey, have i vented certain new and useful Improvements in Combined Type-Writing and Adding Machines, of which the following is a specification.

Combined typewriting and adding machines are necessarily so constructed thatwhile a minimum of amount of power is required to operate the typewriter keys and connections alone, the power to operate these parts in connection with those ac tuating the adding mechanism is necessarily much greater, and efforts from time to time have been made to reduce the power required for operating the combined machines to about that required to operate the typewriting mechanism, or in other .words, each mechanism has been provided with numeral keys from which the adding and recording mechanisms have been actuated and the effort has been to so construct such machines that the numeral keys of the adding machine will not require the exertion of any greater power to operate them than do those of the typewriter This is the purpose of my invention here-' inafter set forth and to this end I make use in connection with independent typewriter keys of a motor, and driving shaft or other continuously moving actuating means operated therefrom, normally out of operative connection with the working parts of the machine but capable of being operatively connected therewith to operate both the recording and adding means by the power of the motor upon moving any one of a series of numbered parts which I term starters as they do not actuate the said mechanisms but merely set parts in position to coact operatively with the motor together with devices which may be used also in connection with other recording machines. as fully set forth hereinafter.

In the accompanying drawings, Figure 1 is a side elevation of sufficient of a combined typewriting and adding machine to illustrate my invention Fig. 2 is a partial plan view of some of the parts; Fig. 3 a detached view showing the arrangement of spring for lifting a starter; Fig. 4 is a plan view of the machine, only a portion of the parts connected therewith being shown.

For the purpose of illustrating my invention, I have shown parts of a combined typewriter and adder which are not my invention, and which may be of any suitable construction, and some features of my invention may be employed with typewriting machines alone or adding machines alone wherever it is desired to utilize a continuously operating motor power for operating the parts of the machine except the starters or the first movements thereof. I

The typewriting features comprise the usual lettered keys Z" and the numeral or numbered keys A connected with sliding frames from which connecting rods 100 extend to type levers 101 so that on pressing a key A the corresponding type lever will be thrown toward the platen P, a spring 100 restoring the parts to position.

The adding devices are operated from a series of numbered starters B, each having a rack102 engaging a pinion 103 with which turns a cam 104 that operates to vibrate a lever 105, the latter on its first -movement being shifted longitudinally and thrown into gear with a pinion 106 connected with the accumulating wheel.

\Vhile various other appliances are used in connection with those described, in the actual operation of a combined typewriter and adding machine, it will not be necessary to set'them forth or describe their operations in detail, as they may be of any de-- sired character, and as my invention is limited to the means whereby the desired movements are imparted from a continuously moving motor to the parts described, that isto both the recording and adding mechanisms.

The motorM is of any suitable character and operates the working shaft 25 of the machine through the medium of a friction device 108 or clutch of any character tha will insure the shaft 25 turning with the motor shaft 109 when the shaft 25 is released, but which will permit the motor shaft to turn independently of the shaft 25 when the latter is prevented from turning.

The shaft 25 is held at rest by a suitable detent, for instance, a pawl or detent '88 pivoted to any fixed support and having a stud 87 which engages the shoulder 29 of a disk 34 on the shaft 25 and holds the said shaft and parts connected therewith in normal or inactive position, a spring; 92 con nected with the pawl 88 carrying ittowardthe disk. When the pawl 87 is moved from the disk, the shaft 25 will remain in clutched relation to the shaft 109 and can turn in the 5 direction of the arrow,,and performthe re quired operations of the mechanism; and

after a complete 'revollition, the shaft andbodied. Inthe construction shown the de-' pressionof each starter B brings aninclined 2o face 67-at the edge of the starter bar or stem against the end ofvan arm 65 secured to a rock shaft 63. arm 76 a*nd a pawl 7 8 pivoted to. the lower end of thisarm'has-its forward end held downward in contact with a stud 83' on the dete'nt 88 by the action of a spring 80. The

pawl 78 has a shoulder that engages'the stud of the detent 88. and when the rock shaft 63 is moved sothat the arm 76 is so drawn backward the detent 88 is carried away from the shoulder 29 of the disk 34 to permit the movement of the latter.

I The rotation of the shaft 25 is the means of operating the 'addingand recording de- 35 vices by carrying the starter B farther downward afterz; the detent 88 is shifted out of position". This may beeflected by differentmeans, but as shown, a link 91 'conjnects a wrist-pin on the disk 34 with a 40 framehaving shaft 36,wliich,arms each carrya stud-41 at the'rearward end, andbenaththis stud hook of a pawl 59 pivoted to the stem of each key Bis brought as soon as thestarter i5 is carried downward to a slight extent To eflect this 'last named result, the pawl 59 has a tail e5 which extendsbeneath an arm; ll-2 projecting from a fixed shaft 43, and a sprmg 58 connected at the ends to thepawl 6b and to the stem of the key B tends to maintain the tail 'against the arm 42. "Consequentl as the starter B descends, the hooked Bndo the pawl will swing forward to a position beneath the stud 41 and when the as diet: B-is released the arms swing. down- :ward hy the rotation of the disk, the engage-- inept of the studwith the hook oithe pawl s-i; l carry the starter, downward its full stroke and effect the operations of-the comso pitting mechanism. As thfarms 90 rise, the contact of the tail-4'5 of the pawlt'oa with the arm 42 will swin thepawl to the posibion shown in the drawing and out of contact with the arm 90., Prior to this,how-

to ever, the rising of the starter ;B- carries the of a'sprin'g 159 in a direction Said shaft carries an.

arms 90 supported on a rock brought to and inclined face 67 from the arm 65, so that the shaft 53 can rock under the action arm 7 6 forward to its first position.

In a'combined computing and typewritmg machine, the typ'ewriting numeral keys must be carried down at the same time that the adder mechanism is operated,and means are therefore provided for also. putting each numbered writing key into connection with I the motor, as by means of; the power actuated to carry the arms 90, while allowing the numeral writing keys to be operated independently. The means for eifecting this, as shown, is a hooked pawl 70 pivoted to theframe of each numbered typewriter key A and slotted to receivea stud 47 on the pawl 59 of the co acting adder key, so'that when the pawl 59 is swung forward, the pawl. 70. will also he swung forward and its hooked end will be brought below the stud 11 which willengage the same and carry down the type key A.

i The starters B are restored to position by means of springs 96 connected to studson the keys and to studs on standards in the frame of the machine. As the disk 34: rotates after being released, a-stud 86 thereon is brought-"beii'eath and elevates the'pawl' 78,'so that it escapes from the stud 83 of the detent 88 which can then swing to a'position for its stud 87 to make contact with the shoulder 29 whenthe latter arrives in position to meet it, Y

While I have referred to a continuously rotating driving shaft-25, and to a rocking working shaft, it will of course be understood that the said driving shaft may be operated by a reciprocating slide or other equivalent working element connected with the mechanisms of the machine.

It will be seen from the above. that while the numeral typewriter keys maybe operated without anymore exertion than in ordinary typewriting, and independently ofthe adding mechanism, the starters can be operated with as little or even less exercise of power by the operator, as they do -not actuate the adding devices but after the parhat depression of-any one, of the starters the further operations are performed by the continuously moving motor until-they are completed, when the working;,parts will be automatically arrested in normal positions. a
